Who has suggestions/sources for folding kayak skins?

If it's a commercially made boat, contact the manufacturer. I don't
believe there is anyone making aftermarket skins for commercial folders.

If it's a boat you're building, post your question on the Kayak Building
Bulletin Board at www.kayakforum.com and on the Greenland Forum at
www.qajaqusa.org. Tom Yost, a well known folding boat builder, hangs out
on these forums and can direct you to material suppliers and
directions for fabricating your own skins.
